DESCRIPTION

The IRF3546 dual integrated Power Block copackages two pairs of high performance control and synchronous MOSFETs and is ideal for use in highdensity two-phase synchronous buck converters. It is optimized internally for PCB layout, heat transfer and package inductance. Coupled with the latest generation of IR MOSFET technology, the IRF3546 provides higher efficiency at low output voltages required by cutting edge CPU, GPU and DDR memory designs.
